science of Natural History, with reference to its injury to the science 

 of classification. I have perhaps strayed from my immediate 

 object in mentioning it now, though I hope some day to recur to 

 it again. To return to our present subject, I by no means stickle for 

 the use of the words " common," " rare," &c., in the senses in which 

 I have now used them ; I only throw out these as hints, and should 

 like to see such practical entomologists as my friends Frederick Bond, 

 H. Harpur Crewe and Edwin Shepherd, &c., putting forward in your 

 pages the senses in which they use and understand these or equivalent 

 words. Local lists, even with all this, and much more care, 

 will yet be imperfect, but without it they will be both practically and 

 theoretically valueless towards the great object of such lists, the con- 

 structing a scientific system of distribution and relative abundance of 

 species.
